OK. I was mildly obsessed over meeting Mr Slope Guy for the first time.
I was observing two novice teachers, and they were using Mr Slope Guy as a mnemonic for students in analyzing slope. But I think he could be fated for bigger and better adventures. Since my son Xavier is a budding comic book artist, we put together the following (PDF of the whole comic), with some inking support from Ysabela.
The problem was whether MSG was a hero or villain, and he wound up needing to be defeated. He is a personification of algebra.
Be interested in your feedback. Only one more thing to say: Marvel, please don't sue! Spider-man is a wholly owned trademark of Marvel, created by Stan Lee and Steve Ditko, and starring in a major motion picture this summer.
